Abstract: PURPOSE:To obtain the matrix substrate having excellent display characteristics by discontinuing the impurity sticking to a semiconductor layer and in contact with a substrate and the impurity in contact with a lower metallic film as the semiconductor layer and a specific transparent conductive film are electrically connected. CONSTITUTION:Picture element electrodes 201 which are transparent conductive film electrodes and scanning electrodes 211 are formed by a sputtering or vacuum vapor deposition method using ITO on the glass substrate 101. The lower metallic film 301 is in succession formed by a sputtering method, etc., using Mo, Ta, Cr, MoSi2, etc., and the metallic film 301 then the electrodes 201, 211 are patterned by a photolithograhic method. The metallic film 301 is overhung by, for example, about 500Angstrom  from the electrodes 201, 211 in this case. The a-Si semiconductor layer 400 is in succession formed by a plasma CVD method and finally, the upper metallic film 701 consisting of Al, Mo, etc., is formed by sputtering, etc., and is patterned by the photolithographic method. The impurity layer 411A is, therefore, discontinued by the overhanging of the metallic film 301 and the generation of a photoelectric current is obviated.

IPC: H04N5/225
Filed: 1993-09-28
Abstract: PURPOSE:To prevent the overload of current even if external power is used while a stroboscope is charged and to shorten time until charging completes by controlling a current amount flowing in the on-period of a switching transistor on a primary side based on voltage rising with the remaining voltage/ charging operation of a main capacitor. CONSTITUTION:The emitter current of a switching transistor 82 is controlled in accordance with the charging voltage value of the main capacitor 83, which is detected by an impedance conversion element 84 and division resistances 85 and 86 after the charging operation is started. Namely, the secondary side voltage of a charging circuit 81, namely, comparison voltage corresponding to the charging voltage of the main capacitor 83, is inputted to a comparator 87 by resistances 90-92. The resistant values of the resistances 90-92 are selected so that comparison voltage rises in accordance with the rise coefficient of charge voltage. Thus, charging current in the charging on-period of one period increases in proportion to the charging voltage of the main capacitor 83.

Title: Electron gun for image pickup tube
Inventor: KUMADA SEIJI
IPC: H01J29/50
Filed: 1992-09-10
Abstract: PURPOSE:To prevent the occurrence of grid emission without remarkably changing electrical field distribution around a grid electrode by providing a layer formed mainly of at least one of In, Sn and Zn oxides on the grid electrode. CONSTITUTION:An oxide layer 40 comprising a mixture of In2O3 and SnO2 is formed on the surface of the second grid G2. In the case of an electron gun having such a grid G2, even when Ba and BaO evaporated from a hot cathode body structure adhere to the second grid G2, the activation thereof is blocked by the oxide 40, and a drop in work function can be prevented, thereby restraining the occurrence of grid emission. When the thickness of the oxide 40 does not exceed 5mum, the separation thereof from the second grid G2 does not occur at all. Also, thickness equal to or above 20Angstrom  is enough to have an effect for restraining the occurrence of grid emission. Furthermore, the oxide 40 has electrical conductivity and, therefore, does not cause a change in the distribution of electrical field around the second grid G2.
